While waiting to return to his adoptive country of France while exiled during the French Revolution, Abraham-Louis Breguet intensely worked on a large number of inventions. June 26th, 1801 will become a milestone for the House of Breguet as the watchmaker obtained a new certificate for a new regulator called « Tourbillon » which he receives for ten years. In 1810, he also creates the first wristwatch for the Queen of Naples and, one decade later, the chronometer with double observation seconds, the ancestor of the modern chronograph.
